Specification of Letters Patent.

Patented June 11, 1907.

Application iiled April 24,1906. Serial No. 313,433.

To @ZZ wiz/0m t may concern:

Be it known that I, ADOLPH LANG, aciti- Zen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Vater-h'iotor, of which the following is a specification.

rlhe object of my present invention is to construct a water motor in such a manner that the water will have a substantially free passage therethrough and which although of simple and compact construction may be operated under a low head and give reliable and eilicient results under all conditions which may arise.

'.lo the above ends my invention consists of a novel construction of a water motor in which the movements of the actuating piston are controlled by a novel construction of a slide valve, the movement of said slide valve being controlled. by a throw valve, which is adapted to be actuated by the piston rod of said piston.

It further consists of a base Vsubdivided into two chambers, one of which constitutes thc feed chamber and the other the exhaust chamber, said chambers being so constructed as to permit the retention of any foreign matter in the water in order that the operation of the motor may never be impeded or interfered with, in combination with a novel construction of a slide valve having a feed area thcrearound and a chamber therein, the exhaust water passing through said chamber and through exhaust ports in said valve and in the casing in which it is mounted.

It further consists of novel means for preventing the rotation of the slide valve employed.

It further consists of a novel construction in which the slide valve is mounted directly above the inlet and exhaust chambers, the piston casing being mounted above the slide valve, the slide valveand the ends of the slide valve1 casing being provided with lugs, thereby forming chambers in which any sediment or foreign material will be collected, so that the same may be readily removed when desired witho ut dismantling the entire motor.

It further consists of a novel construction and arrangement of ports and passages whereby the different valves and pistons and .slide valve in detached position.

their adjuncts co-operate to accomplish the desired result.

It further consists of novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown one form of machine as this embodiment best illustrates the principle of my invention, although it is obvious that the principal instrumentalities of which my invention consists can be variouslj.T arranged and organized and in the accompanying drawings, I have shown one embodiment thereof which I have found in practice to give satisfactory results, although it is to be understood that my invention is not limited to this specific arrangement and organization of these instrumentalities.

The operation of the motor will. now be readily apparent and is as follows2-llaving the parts in the position seen in Figs. 3 and 4, the water from a suitable source of supply enters through the inlet 3, and passes into the inlet chamber 6 in the casing 2 thence through the port 36 into the chamber 12, around the annular groove or neck 14 of the slide valve 13, through the port 52 into the piston chamber 53 and acting on the piston head 54 causes said head and the piston rod 55 carried thereby to move upwardly into the position indicated in Fig. 11. The water above the piston head. 54 will exhaust through the chamber 74, passage 73, conduit 75, port 77, thence through the port 19 which at this time registers therewith, into the chamber 21 of the valve 13, thence through the port 25 and port 37, which it is understood is now open to the exhaust liuid, the Water exhausting tln'oughsaid port 37 into the chamber 7 and then through the outlet 4 as will be apparent` As the piston rod 55 moves upwardly, the rod or bar 66 carried thereby and to which the rod or shalt 63 is secured will cause this rod 63 to move in unison therewith. As the piston head 54 approaches the upper end of the piston chamber 53 the block or bracket 7 0 carried by the rod 68 will engage the set collar or boss 49 on the valve stem 44 and cause said valve stem and its adjuncts to be raised, the parts now appearing as seen in Fig. 11. Having the parts in the position seen in Fig. 3 and 4, the slide valve 13 is maintained in position owing` to water passing from the inlet port 36 around the annular groove 14, thence through port 30, passage 81 and port 32 into the throw valve chamber 40 and thence through port 33, passage 34 and port into the chamber 12, the pressure ofthe water being exerted against the end of the slide valve opposite the throw valve casing 32. As the throw valve 41 moves upwardly, the head 43 will uncover the port 36 and the head 42 will pass above the port 33 so that water entering through the inlet port 36 from the inlet chamber 6 may now pass around. the annular groove14, through ports 30, passage 31 and port 32 into the throw valve chamber 40, and since the throw valve is now in the position as indicated in dotted lines in Fig. 3 and Afull lines in Fig. 11, this water will pass through the port 36 and acting against this end ol. the slide valve will cause the same to move to the opposite end of the slide valve chamber 12, so that the lug 27 abuts or is seated against the lug 31, the water in rear oi' the slide valve exhausting through port 35, passage 34 and port 33 into the throw valve chamber 40, thence through port 90, passage 91, port 37, passage 33, port 39 around the annular groove 22 and through the exhaust port 37 into the chamber 7 and thence to the outlet 4, the parts now being in the position seen in Fig. 11. The water entering the inlet 3 passes into the inlet chamber 6, thence through port 36 around the annular groove 14 or the slide valve 13 and since the head or bearing 16 has now moved beyond the port 52 so that the port 77 conimunicates with the chamber formed between the groove 14 and the walls of the casing, the water will pass through port 77, conduit 7 5, passage 73, chamber 74 into the piston chamber 53 and acting against the piston head 54 will cause the same to move downwardly to the position seen. in Figs. 3 and 4. The water below the piston head 54 will exhaust through port 52, port 24, chamber 21, port 25, exhaust port 37, exhaust chamber 7 and thence to the outlet 4. As the piston head 54 moves downwardly, the piston rod 55 will cause the bar 66 to move downwardly and IOC thereby' the rod 68. The plate or blocl; 70 slides treelv on the valve stem t/fl., which remains in its raised position until said block contacts with the set collar or boss 48 on the stem 4, whereupon said stem and the throw valve al will be moved downwardly Vtroni the position seen in Fig. ll to the position seen in Figs. 3 and 4. The head #L2 will close the port and open the port S3, the head E will pass below the port S6, so that the water may exhaust through port S6 in the throw valve chamber 10, thence through port 92, the passage 9]., port S7 to the exhaust passage 88 and thence through port S9 around the annular groove 22, through the exhaust port 37 into the exhaust chamber T and thence to the outlet 4. The water which changes the slide valve will pass from the inlet chamber 6 through the port 236, around the i annular groove 1J; of the slide valve 13, thence through port SO, the passage 51 and ports S2 into the throw valve chamber y-l0, thence through ports S3, passage Slt and port S5 to the rear ot the valve and cause said slide valve to assume the position seen in Figs. 3, 4, G and 7.

Although in the present instance I have shown a hollow slide valve having portions thereof laced oil in order that the angle plates engaging therewith will prevent rotation of said valve, it will be apparent that this slide valve ma v be otherwise mounted therein, it being onl)v essential that there be ports therein through which the exhausting [luid mav pass and it is evident that the means employed tor preventing` the rotation oi this valve ma)v be varied according` to the conditions and requirements.

It will be apparent that the length olV the stroke of the piston rod 55 niav be'varied as desired b v adjusting the set collars-iS and dit) on the valve rod 44', thereb)r var ving accordinglv the time at which the throw valve is actuated which controls the admission and exhaust ot lluid to actuate the slide valve, which latter controls the admission and exhaust ot tluid to the piston chamber to actuate -the piston therein, and owing to the positive manner in which this throw valve is actuated, the admission and exhaust ot fluid to the motor will be controlled in a verv accurate manner.

The diH'erent parts ot the motor mav readil v be assembled and disassembled when desired. It will be also apparent that in some cases, I mav dispense with the lugs either on the ends et the piston or the ends ot the slide valve casing, since the same are not essential under all conditions.

Owing to the construction and arrangement ot the ports in the throw valve casing and the passages leading therefrom and the chamber formed between the heads t3 and 42 in the casing 32, the throw valve chamber is always open to the entrance ot iced water to control the movement of the slide valve.

It will be further apparent that either the slide valve or throw valve niav be readily inspected. at an v time without dismantling the entire device.

Owing to the construction ot the inlet chamber 6, the greater part ot the foreign material contained in the water will be deposited therein and owing to the provision ot the lugs on the end ot the slide valve piston and the lugs carried bv the end of the slide valve easing, chambers will be harmed at each end ol the slide valve casing in which sediment or other loreign material may collect without interfering with the operation oll the siide valve. in the present instance, I have shown as niv preferred lorm, a construction in which the slide valve casing is located intermediate the inlet and the exhaust chambers and the piston casing, although it will be apparent thaV .l mav assemble and correlate the parts in a ditl'erent manner and still be within the scope ot mv invention. The stroke ot the throw valve niav be adjusted in a varietv of wavs, either bv adjusting the rod (i6 on the piston rod 55 b v ineans of the set screw (5T, or tbv adjusting the rod or bar 68 in the arm or rod (56, or b v adjusting the set collars '1l-S and el() on the throw valve rod at-l. It will thus be apparent that my invention in its broad scope comprises a reciprocating piston, which is controlled bv means ot a novel construction of a slide valve around which the inlet water passes and through which the exhaust water passes to actuate said piston and a novel construction ol a throw valve tor controlling the passage ot water to actuate the slide "alve,- said throw valve being operativelv connected with the piston rod, and means being provided tor preventing the rotation olf said slide valve.

lt will he apparent .from the toregoing that l have produced a novel and useful construction ol water motor which embodies the leatures oi' advantage enumerated in the statement ot invention and the above description and while lf have, in the present instance shown the jireiierred embodiment thereol", it willbe apparent that it is susceptible oi" modification in various particulars without departing trom the spirit and scope ot the invention, or sacrificing any of its advantages. in. the present instance, I have shown the passages through which water passes to actuate the slide valve as being composed ot separate pipes having engagenient with di'tierent parts ot' the casing, but it will be apparent that these passages inalv be lormed in the slide valve casing and still be within the scope ot mv invention Having thus described mv invention, what 1' ciaim as new, and desire to secure b v Letters Patent, is:-
